Abstract
The present invention relates to a carriage turn platform for tunnel construction vehicle. It is composed of slope plate, upper plate, bottom plate and mechanically-driving device. Said mechanically-driving device is equipped with roller-set driven by construction carriage self-body power. Each set of rollers is composed of driving roller and driven roller, and said driven roller uses a suspended structure. Its mechanically-driving device also is equipped with a ratchet one-way stopper, and between upper plate and bottom plate a rolling bearing support and slide block support combined structure is used. Said invention raises working efficiency, and ensures construction safety.
Description
The present invention relates to a kind of vehicle turning platform for tunnel construction.
Vehicle turning platform for tunnel construction is in various tunnels, the roadway excavation process, when unidirectional trackless haulage vehicle transports ballast and material, avoids reversing to advance the inconvenience of (or going out), or constantly excavate the head end operation space in the hole, strengthens the construction working amount.Present employed vehicle turning platform for tunnel construction is made up of motor, mechanical driving device, last dish, chassis, ramp etc.After Construction traffic was driven turntable, by Motor Drive, the power of motor turned round with respect to the chassis by the dish of going up that a cover mechanical driving device drives turntable.Its shortcoming is that turntable needs the special messenger to handle, and turntable needs the exterior power source motor.The tunnel extends, the turntable follow-up, and power line also will extend, and causes very big trouble; In the tunnel, especially bottom surface, tunnel execution conditions are poor besides, and the fragile electric wire of stone riprap muddy water causes electric leakage, brings dangerous.
The objective of the invention is at above-mentioned deficiency of the prior art, and a kind of last vehicle turning platform for tunnel construction that coils with respect to the chassis back rotation that leans on the power drive turntable of Construction traffic self is provided.
The object of the present invention is achieved like this, and it is made up of ramp, last dish, chassis, mechanical driving device.Mechanical driving device is provided with by the power-actuated roller set of Construction traffic self, and every group of roller is made up of driving rolls and return idler, and return idler adopts floated structure, and mechanical driving device also is provided with the ratchet one-way stopper.Adopt rolling bearing supporting and sliding bearing to combine between last dish and the chassis.
Roller set is 4 groups, and the window place at position respectively installs two groups before and after last dish.
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a B-B sectional view of the present invention.
Fig. 3 is a mechanical driving device principle schematic of the present invention.
Fig. 4 is the supporting slide block structural representation.
Fig. 5 is the vertical view of Fig. 4.
Fig. 6 is the left view of Fig. 4.
Fig. 7 is the supporting and the suspension structure schematic diagram of return idler.
By Fig. 1,2 as can be known, the present invention by ramp 1, on coil 3, chassis 2, mechanical driving device form.Mechanical driving device is provided with by the power-actuated roller set of Construction traffic self, and every group of roller is made up of driving rolls 4 and return idler 5, and roller set is 4 groups, respectively installs two groups at the window place at last dish position, 3 front and back.Return idler adopts floated structure, and mechanical driving device also is provided with the ratchet one-way stopper, adopts rolling bearing supporting and thrust slide supporting to combine between last dish and the chassis.
By Fig. 2,3 as can be known, mechanical driving device is made up of driving rolls 4, return idler 5, chain wheel driving mechanism, worm gear, worm gearing, gear drive and ratchet one-way stopper, driving rolls 4, ratchet 20 and minor sprocket 10 are installed on the axle 12, hinge wheel 15 and worm screw 16 are installed on the axle 25, worm gear 17 and pinion 18 are installed on the axle 26, axle 26 is vertically mounted on the dish 3 by bearing, and bull gear 19 is fixed on the chassis 2, and axle 12 and axle 25 are contained on the dish 3.Among Fig. 3,11 is bolster.
By Fig. 1,2,4,5,6 as can be known, the structure of the rolling bearing supporting 6 between last dish 3 and chassis 2 is vertically mounted on the chassis 2 for its axle 29, and be positioned at the center of bull gear 19, last dish 3 is installed on the axle 29 by rolling bearing, supporting slide block 7 between last dish 3 and the chassis 2 adopts the polytetrafluoroethylene (PTFE) slide block, and slide block 7 is fixed on vertical gusset 8 on chassis.Among Fig. 1,9 is horizontal gusset.The upper surface of slide block 7 and both sides all can be supported, and do relative motion with certain part of last dish 3, and its friction factor are little.
By 7 as can be known, the bearing support 22 of floated return idler 5 is fixed on the dish 3 by disk spring 23, forms suspension structure by disk spring.21 is the return idler axle among the figure, and 24 is the disk spring seat, and 27 is bearing.When Construction traffic front-wheel process return idler 5, depress disk spring 23, allow it pass through; When trailing wheel I shelves were opened last two rollers, suspension structure played barrier effect, and vehicle is left.
Operating principle of the present invention is as follows:
Construction traffic is opened going up on the dish 3 of turntable, trailing wheel is pressed on driving rolls 4 and the return idler 5, rear wheel drive roller 4, driving rolls 4 drives axle 12 and rotates, minor sprocket 10 on the axle 12 drives hinge wheel 15 and 16 rotations of coaxial worm screw by chain 4, realizes one group of deceleration; Worm screw 16 drives worm gear 17 and coaxial pinion 18 rotates, and realizes double reduction; 18 groups of pinions are realized three grades of decelerations with respect to 19 rotations of motionless bull gear.Pinion 18 can be considered and then rotation of one with last dish 3 and the vehicle that is parked on the dish 3, promptly finishes the tune of vehicle.The ratchet one-way stopper is made up of ratchet 20 and ratchet 13, and the effect of ratchet one-way stopper is after vehicle is finished tune, when turntable is driven down in reversing again, driving rolls 4 is maintained static, and is convenient to vehicle backing and drives down turntable.
Advantage of the present invention is to have overcome dangerous and electric that the Motor Drive turntable brings Hurdle follow-up and the shortcoming that needs the special messenger to handle have improved operating efficiency, have guaranteed construction safety. It is a kind of comparatively ideal tunnel Construction traffic turntable.
